This chapter describes how to install Caché on a macOS system. It assumes that you are familiar with Mac directory structures, utilities, and commands. This chapter contains the following major sections:

This section describes the hardware and software requirements for installations of Caché.

Disk Space Requirements

A standard Caché installation that includes support for Caché Server Pages (CSP), needs approximately 1 GB (gigabytes) of disk space depending on the type of installation you choose.

Supported Platforms and Web Servers

The latest version of Caché is supported on the macOS operating system on Intel. For macOS, the Caché Server Pages (CSP) technology is supported on the Apache and Nginx web servers. For current information, see the Supported Technologies chapter of InterSystems Supported Platforms.

Note:

When installing Caché and Ensemble, a private version of Apache is installed to ensure that:

The Management Portal runs out of the box.

An out-of-the-box testing capability is provided for development environments.

If using CSP, you must install the web server before installing Caché for the installation to configure the web server. Its support on each operating system is dependent on the operating system vendor and is subject to change. See the Web Server Configuration section of the CSP Configuration chapter of the Using Caché Server Pages guide for more information.

Make the following adjustments if you are running a system that requires a large number of processes or telnet logins:

Remote connections  The number of pty (pseudo terminal) connections is limited to 128 system-wide. If your applications count on telnet or other pty-using connections for users to access, keep this in mind.

Number of processes  If the pty limit is not a problem, but you need to run a larger number of processes, there are limits to that as well.
